METALLIC LATHING AND FIREPROOF CONSTRUCTION FOR BUILDINGS.

SPECIFICATION forming part of Letters Patent N 0. 658,497, dated September 25, 1900.

Application filed November 23, 1899. Serial No. 737,988. (No model.)

To all whom/it may concern: 7

Be it known that I, MARTIN OARRIoK, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in Metallic Lathing and Fireproof Construction for Buildings; and I hereby declare the following to be afull, clear, and exact description of the same.

My invention relates to lathing and finishing forbuildings of that class known as metallic and fireproof finish.

The object of my invention is to provide for the construction of complete walls, ceilings, and partitions in which spaces are provided for deadening sounds, means for protecting the plaster and making the construction vermin-proofiand means forproviding air and ventilating spaces and passages through which conducting wires or pipes may be carried.

The invention is an improvement upon Patent No. 591,207, issued to me October 5, 1897, and comprises certain forms and details of construction not shown in the said patent.

Referring to the accompanying drawings, Figure 1 is a perspective view showing an inner angle of a room and illustrating the construction of the floors, walls, and ceilings. Fig. 1 shows floor construction without floortimbers H. Fig. 2 is a horizontal section taken through a wall. Fig. 3 shows the arch structure. Fig. 4 is a vertical perspective of the wall. Fig. 5 is a vertical section transverse of the I floor-beams, showing the floor and ceiling construction, respectively, above and below the same. i

The lathing consists of sheet metal A cut into any suitable size, having long horizontal slits which are punched through the sheets, leaving one or more edges united with the sheet, so that the intermediate portion or portions may be turned inwardly at approximately right angles with the face of the sheet, so as to form shelves or bonds by which the plaster is locked in place and is also prevented from falling inside, this construction being well shown in my former patent.

If the lathing is to be put upon the solid Wall, the sheets are bent to form vertical inturned grooves a, as shown in Fig. 2, and these inturned port-ions resting against the quired mortar space.

Wall serve to hold the sheets of lathing far enough away from the wall to leave the re- Nails are driven through these grooves to secure the sheets to the Wall, and at the ends each sheet has a similar bend, which may overlap the next adjacentsheet, so that a single nail driven through the overlapping angle holds the two sheets t0gether.

When the sheets are to be put together to form a partition, the channel-irons B form vertical supports and are held in position attop and bottom by short angle pieces or brack ets b. To the outside of the channel-irons B are fixed wooden strips D, and to these lat ter are nailed the lathing-sheets. Additional metal strengthening strips 0 extend horizontally through the partition between the wooden pieces D and the channel-irons B.

When the lathing is to be secured to form arches, the I-beams (shown in Fig. 5) are connected by angle-iron strips E, to which the wooden strips D are secured, said strips E being secured at each end to the I-beams by I the angle-brackets b, and the bands F and the sheets are secured to these angle-irons by wires or in any suitable manner.

The floor and ceiling are constructed in the following manner: The I-beams Gr are at certain intervals inclosed by metal bands F, and to these bands are secured the angle-irons F. by the usual bracket-pieces b, so that the upper and lower edges of theangle-beams E are in any desired position with relation to the top and bottom of the I-beams G. To these angle-irons are attached the supplemental strips e, extending horizontally and standing edgewise, with their upper edges projecting above the tops of the beams G, as shown. The meeting ends of the strips 6 overlap above these beams G and are fastened together. Upon the strips e, as shown, and the angleirons E and eitending at right angles with them are the wooden timbers H, to which the flooring M is nailed. The timbers. H are grooved or channeled on the under side, so as to fit over the edges of the upwardly-projecting strips e, and they alternate, so that the ends of the timbers H maybe nailed through the strips e, and when the concrete has been filled into the spaces, as will be hereinafter described, it will be made level with the top of the strips e, and there will be a space left between it and the flooring M equal to the depth of the beams H above the tops of these strips. This space allows a circulation of air and ventilation, which will prevent the deterioration of the floor-boards by moisture, and it also provides space for the running of wires K, pipes, and the like. When the floorsurface is to be finished in concrete, the ti mbers may be omitted and metal strips like H, Fig. 1, substituted. In either construction the surface of the concrete is divided into smaller sections and is not liable to become cracked. Apertures I, Fig. l, are made through the extensions 6 and bars E, so that the concrete may pass through from one side to the other and form a bond for the whole mass, which is otherwise separated by the beams. A wire 0 may be passed around the irons E, going through the lathing in the center for additional strength. The lathing is now attached to the structure thus formed, being curved or arched on all sides, as shown plainly in Fig. 5,and extending down to the bottom flange of the beams G. Through the center or at other suitable part a tube or tubes J are passed to admit of the passage of pipes or wires and leading out to the ceiling underneath. The concrete having been filled into a level with the extensions 6, as before described, leaves a space between it and the floor above. The ceiling below is formed in the same manner as described for the partitions. The bands F, which surround the I- beams G, have fixed to their lower ends the angle-iron bars E by brackets b, and to these irons are attached wooden strips D, similar to those described for the vertical partitions, and the strengthening-bars G extend at right angles to the strips in the same manner. To these are secured the lathing, which forms the flat ceiling below, and this leaves a large empty space between this surface and the bottom surface of the concrete and iron structure, which forms the upper part, as pre viously described. V.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- 1. The combination with parallel channel or I beams, of transverse beams abutting therewith, bands surrounding the first-named beams and angle-pieces or brackets by which the abutting beams are secured thereto.

2. The combination with parallel floorbeams of bands surrounding and fixed to said beams, transverse beams extending between the main beams, and brackets by which the transverse beams are secured .to the bands.

3.
